A jury delivered the verdict in David Gladstone's trial Tuesday afternoon before Lansing District Judge Charles Filice, MLive media partner WLNS-TV 6 reports. Gladstone had been charged with misdemeanor assault and battery.

Gladstone, a 20-year veteran of the Lansing Police Department, was suspended and placed on paid administrative leave after he was formally charged on March 22. He allegedly assaulted a teenage inmate at the city's jail on March 8.

Gladstone, 54, of Eaton Rapids, was released on a $500 personal recognizance bond on March 22. His trial began on Monday.

Lansing interim Police Chief Mike Yankowski said Gladstone's fate with the department remains to be seen pending an internal investigation..

"The Lansing Police Department Internal Affairs Unit will
be investigating this matter internally and will determine if Gladstone acted
outside the policies and procedures of the Lansing Police Department," Yankowski said in a statement.

"If the
investigation determines that he violated policies and procedures, penalties
range from a counseling statement to termination, which is per the department's
discipline matrix."

Gladstone was one of four Lansing Police Department employees named in a 2009 lawsuit filed by a man who alleged he was assaulted and battered at the city's jail in 2007. The plaintiff accused Gladstone of shoving him face-first into a door and a wall, then placing him in a chokehold.

The city of Lansing eventually settled the case for $46,500, according to the plaintiff's lawyer.
